【摘要】：介紹了一種基于Y形能量選擇表面的新型電磁脈沖防護(hù)材料,具有能量域上"低通高阻"的特性。對(duì)能量選擇表面的理論基礎(chǔ)和工作機(jī)制進(jìn)行研究,論證了其透波率和外界場(chǎng)強(qiáng)的關(guān)系。通過(guò)建模仿真對(duì)能量選擇表面的防護(hù)性能進(jìn)行驗(yàn)證,并分析其結(jié)構(gòu)尺寸對(duì)防護(hù)性能的影響。設(shè)計(jì)并仿真了雙層Y形結(jié)構(gòu),與單層結(jié)構(gòu)相比,雙層結(jié)構(gòu)對(duì)高功率電磁脈沖具有更好的屏蔽能力,并且保持了對(duì)于低功率信號(hào)良好的透波率。
[Abstract]:A new type of electromagnetic pulse protection material based on Y-shaped energy selective surface is introduced, which has the characteristics of "low permeability and high resistance" in the energy domain. The theoretical basis and working mechanism of the energy selective surface are studied. The relationship between the transmittance and the external field strength is demonstrated. The protective performance of the energy-selective surface is verified by modeling and simulation, and the influence of the structure size on the protection performance is analyzed. The double-layer Y-shaped structure is designed and simulated, which is compared with the single-layer structure. The double layer structure has better shielding ability for high power electromagnetic pulse and good transmittance for low power signal.
